Installing packages into updated R
This is one reason we normally recommend that you install into a separate library. Then update.packages(checkBuilt = TRUE) is all that is needed. However,
foo <- installed.packages() as.vector(foo[is.na(foo[, "Priority"]), 1])
will give you a character vector which you can feed to install.packages(), so it's not complex to do manually.

A minor inconvenience in updating an R installation is remembering which packages were installed previously. Has anyone written a script to inspect a previous installation, then get & install the same packages into the new installation?
